1. Another month, another mass-transit disaster: This latest one, which killed at least seven people in the nation’s capital, was supposed to be impossible, The Washington Post reports. A computer should apply brakes automatically if trains get too close. Another mystery: The driver of the train that crashed had a clear line of sight but apparently never braked, either. Was she incapacitated? Using a cell phone, like the drivers I wrote about last month?

2. Another week, another higher-ed exec getting paid by taxpayers not to work: Tarrant County College Chancellor Leonardo de la Garza has quit with two years left on his contract — but still will receive $700,000, the Fort Worth Star-Telegram reports. The story lacks much context; go to the Fort Worth Weekly for that. Last week, Elsa Murano quit as Texas A&M boss. Here’s her deal, as reported yesterday by my colleague Holly Hacker: “She will be on leave for a year and keep her president’s $425,000 salary, plus an additional $295,000, and she agreed not to sue. She plans to return as a professor, at a $260,000 salary.”
